The food processing industry relies heavily on companies like Nationwide Boiler for providing temporary steam for seasonal production, especially every summer when tomato season rolls around. One report indicates that California accounts for more than 90 percent of the U.S. production of tomatoes and in 2008 the state recorded a $953 million crop. As a food staple, tomatoes can be found in one form of another in most every household and are used in ketchup, pizza and pasta sauce and salsa, and many other products requiring tomato paste.
Nationwide has always taken a proactive approach towards renting equipment to tomato processors located in California's Central Valley. To keep the industry running, it is vital that Nationwide stock an adequate amount of trailer-mounted boilers in anticipation of an abundant harvest, on top of equipment already rented out to customers in other industries. It is also important that Nationwide continually stay in contact with tomato processors well in advance of the start of the season to ensure equipment is available and operating prior to tomato delivery.
One prominent processor located near Modesto, CA recently rented a 70,000 lb/hr trailer-mounted boiler with a CataStakâ„¢ SCR system and an EconoStak economizer. As in previous years, the equipment was delivered as the company was preparing to ramp up production prior to the first tomato-laden trucks rolling in. The addition of the CataStak and EconoStak improved boiler efficiency and the boiler easily met the 5 ppm NOx emission requirement required by the local air district. Not only is Nationwide providing an immediate supply of steam, but the company is also providing an environmentally â€œgreenâ€ solution.
The next time you enjoy ketchup with your fries or when you add an extra scoop of sauce to go with your spaghetti, remember that Nationwide Boiler was involved in making sure those tomatoes made it to your plate, and we expect to continue to do the same - time and time again.
The need to operate a boiler efficiently in today's environment and competitive landscape is at the top of many plant owners and operators list. Unfortunately operating a boiler efficiently while meeting local emission regulations do not always go hand in hand. However, advances in boiler system design and low NOx technology solutions have made this a much more achievable task.
The list below includes 10 tips which can instantly improve overall boiler performance and sustainability, helping to achieve more cost-effective maintenance and operations of your steam system.
This list, along with general guidelines for each, will be published in an upcoming issue of Process Heating magazine. Please email Nationwide if you are interested in obtaining a copy.
1. Reduce Excess Air
2. Install an Economizer
3. Install a Condensing Economizer
4. Upgrade to VFD Fan Controls
5. Install a Selective Catalytic Reduction System (SCR) with a Standard Low Excess Air/No FGR Burner
Nationwide Boiler was recently asked to take part in a survey-type article for the May issue of Power Engineering magazine. The focus was on the latest trends and best practices for burner and combustion system operation and maintenance. Below is our response and it includes where we think the industry is heading.

As a user and a supplier of rental boilers, Nationwide Boiler Inc. has vast knowledge and experience with supplying and servicing equipment. When the company evaluates new equipment for our rental fleet or provides solutions for new boilers or boiler upgrades, we evaluate equipment that is easy to maintain, provides reliable performance for demanding applications, is the most energy efficient and is able to meet the strictest air emission requirements. We cannot risk onsite equipment failures, therefore we only evaluate quality products that provide immediate efficiency gains.
Energy efficiency is and has been a growing trend over the last five years. Best performance standards (BPS) exist today that we view as a basic requirement for any new boiler system. These standards utilize proven methods for achieving the highest thermal efficiency possible, all based on proven technology. One item boiler owners and operators should not overlook is the installation of VFD fan controls, offering instant energy savings when a unit is not operating at its peak capacity.
For proven burner performance, a minimal or no FGR low excess air burner with O2 trim should also be evaluated. This type of burner not only results in high turndown, but also offers better flame stability compared to ultra low NOx burners, utilizing high FGR or excess air, which are often times slow to respond to load swings and can rely on oversized FD fans that increase energy consumption.
For those operators who must comply with ultra low NOX emission standards, we view back-end technology as the most proven solution. Compared to burners, SCRs eliminate burner flame stability concerns, slow response time and high horsepower FD fans required by front-end technology. In most cases there is no need to increase fan sizes or change burner controls and a SCR is a long term compliance solution, able to reduce NOx up to 95% with emissions as low as 2.5 ppm.
In terms of controls, we are seeing more units equipped with fully metered PLC combustion control systems with innovative touch screen operator interface. This removes a lot of the guesswork out of the operation of the boiler and may save valuable field service time. Also, having the ability to monitor operations remotely and gather historical data and trends provide meaningful and valuable information.
Overall, the trend for energy efficiency is not going away. It is important for boiler owners and operators to take a BPS technology approach when faced with a new boiler purchase or boiler upgrade decision. Many plants that have implemented this approach have benefited and Nationwide Boiler predicts that more will follow.
